Hari Sridhar’s recent paper on Mixed-species flocks covered in Indian Express

Amitabh Sinha at Indian Express has a nice summary of Hari Sridhar’s recently published paper on “Friendship across species borders: factors that facilitate and constrain heterospecific sociality”.

Click here for the Indian Express article with the nice title: “Costs and benefits: Why birds of a feather sometimes don’t flock together”. This is how it looks in the newspaper!

(New) Paper on dryland ecosystem transitions and coverage in Deccan herald

Although I have tweeted quite a bit about this paper, I have been rather slow to announce this paper on this blog.

Chen Ning, Kailiang Yu, C Jayaprakash, Vishwesha Guttal, 2018, Rising variability, not slowing down, as a leading indicator of a stochastically driven abrupt transition in a dryland ecosystem, The American Naturalist, 191: E1 E14Data and Codes via Dryad. 

In this paper, we conduct an empirical test of early warning signals in a dryland ecosystem in China. This was based on a very cool email-collaboration with Chen Ning, a graduate student at that time.

The empirical analyses closely match with results of one of my PhD thesis paper with Prof C Jayaprakash, who is also a coauthor on this paper.

Suma from Gubbi Labs wrote this really nice popular article for Research Matters and it was also picked up by Deccan Herald, a very prominent English newspaper in South India !!!!

 


New paper on financial market crashes and media coverage

Our new paper showing “Lack of Critical Slowing Down Suggests that Financial Meltdowns Are Not Critical Transitions, yet Rising Variability Could Signal Systemic Risk” is out in PLoS ONE!

Nature India carried out a very nice article on our work, written by Mr Varma. National University of Ireland, Galway issued a press-release (an initial draft of which was written by Rajashree of Science Media Centre, IISc). and featured it on their website. Here is a media article at Deccan Herald, but whats written there just does not make sense.

This work was done in collaboration with Dr Srinivas Raghavendra, an economist at the National University of Ireland, Galway. We started the work sometime in mid-2012. Nikunj Goel, a Physics undergraduate student at IISc, joined this work in early 2014 and did enormous contributions to the manuscript. Quentin Hoarau, an undergraduate itern from CNS, France, was also a co-author on the manuscript.


Media coverage of our winter school modern finance and macroeconomics

Along with my collaborators Srikanth Iyer and Srinivas Raghavendra, I am organising an ICTS conference on “Modern finance and macroeconimics” from Dec 22nd and Jan 2nd.

We are delighted that our school got a coverage from Deccan Herald, an important newspaper in southern India. My colleague Srinivas Raghavendra and a student participating in the conference are quoted in the article.

In this school, I will be teaching techniques related to our collaborative work on testing predictions of early warning signals of critical transitions in financial markets. This work was done with Srinivas Raghavendra and my former UG students Nikunj Goel and Quentin Hoarau.

And Happy new year to all!


Comments on opportunities for scientific research in India [Updated]

Mr. GBSNP Varma is writing a series of articles in Science Careers (online) section of the Science magazine to highlight opportunities and challenges for scientific research in India. In the part 1 of this series, myself and several of my colleagues and collaborators such as Dr. Maria Thaker and Prof. Sriram Ramaswamy have been interviewed.

Read the article here: Part 1: In India, Abundant Opportunities

My picture in the article in my office was taken by Ashwin Viswanathan, with all of my lab members making fun of how I pose to pictures (and I was nervous)!

Update (12/11/2013): here is the part 2 of the article focussing on challenges of doing research in India.



“Can the collapse of an ecosystem be foreseen?” – by Priyanka Pulla

Priyanka Pulla, an award winning freelance journalist [1], wrote a blog about our work (with my adviser Prof. Jayaprakash) on early warning signals of ecosystem collapses.

Here is the link.

As always, she writes really well (check her blog and her other articles). She also makes some connections to Indian Monsoon and the hypothesis about regime shifts in Monsoon.

[1] Priyanka’s article on Flock Theory and Synchronies of Nature in Open magazine won her the RedInk Awards for Journalism 2013. That article, if you haven’t read, is something you must read! Obviously, that is also relevant to my research work. She had written on the fascinating work of my colleague and collaborator Sriram Ramaswamy at Physics Department (now director, TCIS, Hyderabad). She had also interviewed me to get an ecologist’s perspective.
